CHURN.

SPECIFICATION forming part of Letters Patent No. 364,744, dated June 14, 1887.

Application tiled January 22, 1887. Serial No. 225,161.

To @ZZ whom, it may concern:

Be it known that we, WILHELM A. ZIETZKE and HENRY C. SUMMEEs, citizens of the United States, residing at Bozeman, in the county of Gallatin and Territory of Montana, have invented a new and useful Improvement in Churns, of which the following is a specification;

Our invention relates to an improvement in churns; and it consists in the peculiar construction andcombination of devices,that will be more fully s et lforth hereinafter, and particularly pointed out'in the claims.

In the drawings, Figure lis a side elevation of a churn embodying our improvement. Fig. 2 is a vertical longitudinal sectional view of the churn-body. Fig. 3 is a vertical transverse sectional view of the same. Fig. 4 is a detail perspective View of one of the beaters.

A represents a vertical supporting-frame having the sides r standards B, which are connected together by means of transverse stays or braces C. From the inner sides of the vertical frame, at the corners thereof, pro- 2 5 ject headed studs or pins D.

` E represents 'a rectangular churn-body, which may be made of wood, sheet metal, or any other preferred material, and is provided with a water-chamber, F, which extends entirely around its sides and ends. The sides of the churn-body are provided with sheets or panes of glass, G, so that light may be admitted to the interior of the churn-body when the top or cover thereof is on. This cover H is provided with a depending iiange, I, adapted to fit between the sides and end of the churn-body, and that portion of the projecting iiange or edge of the cover which extends beyond the depending iiange and bears upon the upper edges of the churn-body is provided with a packing, K, made of cork, leather, rubber, or other suitable material, the object of the said packing being to effect a water-tight joint between the cover and the churn-body. The cover is also provided with circular glass panes L, which enable the operator to see the contents of the churnbody,and thus ascertain at a glance whether the butter is formed or not while the operation of churning is in progress. From the bottom of the churn-body,

at the ends thereof, extend faucets M, the func- (No model.)

-tion of which is to draw the buttermilk from the churn-body when the churning operation is completed, so as to leave the butter in the churnbody, where it may be readily worked and salted.

OnV the under side of the chnrirbody, near the ends thereof, are arranged transverse bars N, in the ends of which are secured projecting threaded studs O. The width of the churnbody is such that it maybe placed between the sides or standards of the supporting-frame, and the churn-body is suspended in the frame by means of links P, the upper ends of which are pivoted upon the studs D, and the lower ends of which are pivoted upon the studs O. By means of these links the churn-body is adapted to reciprocate lengthwise to and fro between'the sides of the frame, and also to alternately rise and fall simultaneously with its longitudinal movement, thus effecting a maximum agitation ofthe cream within the churn-body, and. causing the same to be violenti y dashed iirst against one end of the churnbody,and then against the other end thereof.

In the center of the cover is an opening, O, which forms a vent. The cover is securedin position on the upper side of the churn-body by means of a series of clamps, S, which are secured on the sides and ends of the churnbody.` Each clamp comprises a base-piece, T, secured to the churn-body on the outer side thereof, and having the ears t, a curved arm, t', the lower end of which is pivoted between the ears, and a thumb-screw, t2, which engages a threaded opening in the free end of the arm. After the cover is placed on the churn-body, the clamping-arms are turned upwardly to the position shown in the drawings, and the thumbscrews are turned so as to bear downwardly upon the cover, and thus secure the latter iirmly on the churn-body.

U represent-s a pair of beaters, which are placed in the churn-body, cach beater comprising an inclined board, V, having depending supporting-feet V at its ends, which bear squarely against the bottom of the churn-bod y, and at its upper side is provided with a ver tical yoke, V2, which is made of wire, and is adapted to bear against the cover of the churnbody, so as to retain the beater therein in the position indicated in Fig. 2. It will be 0bserved by reference to the said figure that the beaters are arranged in the churn-body with their inclined sides approaching each other, and that the spaces formed under the lower sides of the beaters by reason of the depending supporting-feet constitute channels to admit the free passage of the currents of cream lengthwise in the'ehnrn-body.

In order to prevent the beaters being forced out of place by the action of the cream in churning, the top bar of the yoke V2 niay be fitted in a groove formed on the under side of the lid or held between two pins or stops thereon.

From one side of the churn body, at the ceuter thereof, projects a headed stud, WV.

X represents a rod, which has its upper end slotted and pivoted upon the said stud, the lower end of the said rod being pivoted to one side of the supporting-frame at the bottoni thereof.

Y represents a hand-lever, which has its lower end pivoted on the opposite side from the rod X, the said hand-lever Y being provided, at a suitable distance from its lower end, with a longitudinal slot, Z. A pin or bolt, A', projects from the outer side of the rod X and works in the slot.

In order to operate the churn-body, the hand-lever Y is grasped and moved back and forth lengthwise against one side of the frame, thus imparting an oscillating vibratory motion to the churnhody,and eousequentlyeausing the contents thereof to be violently agitated and churned into butter in *av comparatively short time. The water-space surrounding the sides and ends of the churn-body perinit-s hot or cold water to be placed therein, so as to raise or lower the temperature of the cream in the churn to the requisite degree for securing the best results in churning.

Having thus described our invention, we claiml. The combination of the frame or stand, the depending links pivotally connected thereto, and the churn-body suspended by the said links, and thereby adapted to oseillate, the rod X, pivoted to the stand or frame and connected to the churn-body, and the handlever Y, pivoted to the stand or frame and connected to the rod X, the said rod X having a projecting bolt or pin working in a slot made in the lever Y,substantiall y as described.

2. The beaters arranged ata suitable angle, having the depending feet adapted to bear against the bottom of the churn-body,and provided with the upwardly-extending yokeframe detachably secured to the top of the churn-body, so as to secure the beaters in place, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
